The first and foremost step is to choose the correct ITR form that aligns with your sources of income. 

There are different forms catering to various income profiles, such as ITR-1 for salaried individuals and ITR-4 for businesses and professionals. Selecting the appropriate form ensures that you provide the right information and calculations.

Step 2: Gather Essential Documents

Before diving into the form, collect all the necessary documents. This may include:

  • Form 16: Your salary certificate issued by your employer.
  • Bank Statements: Reflecting your income, interest earned, and other financial transactions.
  • Investment Proofs: Documents supporting deductions claimed under various sections like 80C, 80D, etc.
  • PAN Card: Your Permanent Account Number is a prerequisite for filing an ITR.
  • Aadhaar Card: Mandatory for e-verification of your ITR.

Step 3: Personal Information

The ITR form typically starts with sections for personal information. Fill in details such as your name, PAN, Aadhaar number, and contact information accurately. Ensure that the information matches the details on your PAN card.

Step 4: Income Details

Enter your income details in the relevant sections of the form:

  • Salary Income: If you are a salaried individual, refer to your Form 16 for accurate figures.
  • House Property Income: Declare any rental income or property details.
  • Business or Profession Income: If applicable, provide details of your business or professional income.
  • Capital Gains: Report any profits from the sale of assets like property or stocks.

Step 5: Deductions and Exemptions

In this section, declare the deductions and exemptions you are eligible for under various sections of the Income Tax Act. Common deductions include investments in Provident Fund (PF), Public Provident Fund (PPF), life insurance premiums, and medical insurance premiums.

Step 6: Tax Computation

Calculate your total taxable income by subtracting deductions from your gross income. After this, compute the tax liability using the applicable tax slabs. You can find the tax slabs for the assessment year on the Income Tax Department’s official website.

Before submitting your return, review all the details entered in the form. Ensure accuracy and completeness.
